Measurement of the tensor analyzing power T20 for incoherent π− photoproduction on a deuteron above the first resonance region

open access: yesPhysics Letters B
New measurements of the T20 component of tensor analyzing power in the reaction γd→ppπ− for photon energies 400−700 MeV are presented. The experiment was carried out on an internal tensor-polarized gas deuterium target of the VEPP-3 electron storage ring

Probing alpha clusters in the ground state of 12C via alpha-knockout reactions [PDF]

open access: yesEPJ Web of Conferences
Understanding alpha clustering in the ground state of 12C is crucial in nuclear structure physics. Motivated by recent theoretical indications of a non-negligible preformed α-cluster component, we investigated the 12C(p, pα) reaction under quasi-free ...

Microscopic Insights into Magnetic Warping and Time‐Reversal Symmetry Breaking in Topological Surface States of Rare‐Earth‐Doped Bi2Te3

open access: yesAdvanced Materials, EarlyView.
Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

open access: yesAdvanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

La science-fiction et le champ littéraire

open access: yesReS Futurae, 2015
Le seul roman historique de Flaubert, Salammbô, fut publié en 1862, à peu près en même temps que le premier des Voyages extraordinaires de Jules Verne, Cinq semaines en ballon.

Correlated Charge Transport in an Organic Coulomb Glass

open access: yesAdvanced Materials, EarlyView.
ABSTRACT Advances in the development of organic field‐effect transistors (OFETs), electrically gated organic semiconductors (EGOFETs), and organic electrochemical transistors (OECTs) allow for the operation of these devices at very high charge‐carrier densities, where Coulomb interactions between carriers can be expected to become significant.

Experimental constraints on the ω–nucleus real potential

open access: yesPhysics Letters B, 2014
In a search for ω mesic states, the production of ω-mesons in coincidence with forward going protons has been studied in photon induced reactions on 12C for incident photon energies of 1250–3100 MeV.

A New Approach to Evaluate Regular Semirings in terms of Bipolar Fuzzy k-Ideals Using k-Products

open access: yesJournal of Mathematics, 2022
In this paper, we provide a generalized form of ideals that is k-ideals of semirings with the combination of a bipolar fuzzy set (BFS). The BFS is a generalization of fuzzy set (FS) that deals with uncertain problems in both positive and negative aspects.

Creating a quasi-linear model of an elastic damper support of the gas turbine engine rotor

open access: yesВестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение
In the presented work, the calculation of critical rotor speeds and determination of vibration characteristics of an advanced gas turbine engine are considered. The engine under study contains a low-pressure compressor with an elastic damper support of a
